Using a SAS Data Set to Write SAS Code
By Bob Romero
• Request to see how many subscribers and non
subscribers in each city in the West Division
were being contacted through marketing
campaigns
• Hundreds of marketing campaigns are
generated by marketing analysts in the
western part of the United States
• Files containing customer and potential
customer information reside on server
Use FILENAME statement with ftp and ls options to
download contents into a SAS Data Set
•
libname perm '/export/home/mthompso/Counts/Comet/sasds';
•
•
•
•
•
filename dir ftp '' ls
Host=‘xxxxx'
User=‘xxxxxxxxxx'
Pass=‘xxxxxxx'
cd='DATA_OUT/DM';
Use data step with infile and input to create SAS data set(s)

data ns_datfiles s_datfiles;
infile dir dsd dlm = ' ';
input cometfile : $80. ;
if substr(cometfile,1,4) = '2011' then do;
month = input(substr(cometfile,6,2),2.);
if month = 02 then save = 1;
end;
if substr(cometfile,5,4) = '2011' then do;
month = input(substr(cometfile,10,2),2.);
if month = 02 then save = 1;
end;
if save then do;
if index(cometfile,'_NS') > 0 then output ns_datfiles;
else output s_datfiles;
end;
drop month save;

Include code to run newly generated code
•
•
%include '/export/home/mthompso/COMET/Comet_counts_nonsub.sas';
%include '/export/home/mthompso/COMET/Comet_counts_sub.sas';
• First program is 2,876 lines
• Second program is 6,947 lines
Conclusion
Summarized Data is exported to EXCEL showing
exactly how customers have been contacted in
each locale
Keys to success:
• ls option on filename with ftp
• Files have naming convention
• Every dat file has same format
